说明
简将列表数据转化为树结构
源码
https://github.com/ddzy/ts-utility-plugins/blob/master/src/ddzy/utility/others/listToTree/index.ts
用法
listToTree.test.ts
import listToTree from "../../utility/others/listToTree";
describe('listToTree tests()...', () => {
test('listToTree should transform a list to a tree', () => {
const received = [
{
id: 2,
value: 2,
parent: 1,
},
{
id: 3,
value: 3,
parent: 0,
},
{
id: 4,
value: 4,
parent: 3,
},
{
id: 5,
value: 5,
parent: 3,
},
{
id: 1,
value: 1,
parent: 0,
},
{
id: 6,
value: 6,
parent: 4,
},
{
id: 7,
value: 7,
parent: 4,
},
{
id: 8,
value: 8,
parent: 7,
},
];
const expected = [
{
"id": 3,
"value": 3,
"parent": 0,
"children": [
{
"id": 4,
"value": 4,
"parent": 3,
"children": [
{
"id": 6,
"value": 6,
"parent": 4
},
{
"id": 7,
"value": 7,
"parent": 4,
"children": [
{
"id": 8,
"value": 8,
"parent": 7
}
]
}
]
},
{
"id": 5,
"value": 5,
"parent": 3
}
]
},
{
"id": 1,
"value": 1,
"parent": 0,
"children": [
{
"id": 2,
"value": 2,
"parent": 1
}
]
}
];
const result = listToTree(received);
expect(result).toStrictEqual(expected);
});
});
